because the devs dont feel like adding new content to the game like a new creature or environmental threat, so the only thing they can to make the game harder is to reduce what a crew can have and do, rather than create new threats to consume resources and challenge the players as they are.
As mentioned in the post, there's going to be plenty of new content in this update: the "meat" of the update is going to be the overhauled traitor mode. I think we'll be shedding more light on that in the next blog post. :)
